i am currently running windows xp sp2 32bit on my system but have just purchased windows vista home premium 64bit oem.
the vista will not boot when i put it in while xp is runing , it comes up with not a x32 application try booting directly from cd.
so, i boot direct from the cd (dvd), it all starts okay, it comes to a blue screen then just stops dead and i have to unplug pc to restart ?
can you tell me why this is happening and how to overcome it ?

any help appreciated

Hi hodgey,
Firstly, I'd like to welcome to CompuForums - it's good to have you here. I hope you will be on the board for a long time, and if there is anything I can do to make your experience better please let me know. We are here to help you, so it would be appreciated if you could help us by posting in threads as well as your own. By doing so, you are helping to keep this site running in the future, and we will respond to your thread faster too. But if you can't help us, then we can't help you.

I know this is an obvious question - but does your computer have a 64bit processor?
It's likley that there is hardware you have that is not 64 bit compatible, but it would be useful if you could describe the error on the blue screen.

Like Ash states, most things point towards hardware incompatibilities. Make sure your system is compatible.
